AI Technical Summary
In traditional tractor chassis transmission systems, the travel motor and PTO motor work independently, which cannot meet the power requirements of the travel system under different loads, and the energy consumption is high.
The system employs a transmission system, including an engine, a first input shaft, a travel transmission assembly, a first output shaft, a motor, a second input shaft, a PTO transmission assembly, a second output shaft, and a first clutch. By controlling the engagement or disengagement of the first clutch with respect to the second input shaft and the first output shaft, and in combination with the different states of the travel transmission assembly, power transmission is achieved to meet the travel power requirements under different loads.
It meets the power requirements of the walking system under different loads, reduces energy consumption, and improves the efficiency of the transmission system.
